Plumbing Vent in Outdoor Kitchen

[Off Rez]

I am just wondering if anyone can help me with a plumbing vent that is in the cabinet in the outdoor kitchen on a Coachmen 292BHDS. What is the vent for? I am guessing the fresh water tank, pretty sure it's NOT the black water tank vent, but maybe gray water tank vent? I ask because we have a possible gas leak from the rear of our unit and while investigating I thought it was coming from this vent tube. Thanks! Sorry I don't have a picture to help out.

Coachmen says it's probably a vent for camp kitchen sink
